What does `/ああ/n` represent in this context?

As I stated in the previous comment, I'd like to handle multibyte characters.
For example, `.` should match with a single or multibyte character, not a byte.

How about to add byte-based operations for String?

```ruby
s = "あああいいいあああ"
p s.byteindex(/ああ/, 4) #=> 18
x, y = Regexp.last_match.byteoffset(0) #=> [18, 24]
s.bytesplice(x...y, "おおお")
p s #=> "あああいいいおおおあ"
```
